O you men, serve your Lord Who created you, and those that were before you; haply so you will be godfearing; 21 Worship God who has rendered the earth as a floor for you and the sky as a dome for you and has sent water down from the sky to produce fruits for your sustenance. Do not knowingly set up anything as an equal to God. 22 And if ye are in doubt as to what We have revealed from time to time to Our servant, then produce a Sura like thereunto; and call your witnesses or helpers (If there are any) besides Allah, if your (doubts) are true. 23 But if you fail, as you are sure to fail, then guard yourselves against the Fire whose fuel is people and stones, prepared for the unbelievers. 24 But unto those who have attained to faith and do good works give the glad tiding that theirs shall be gardens through which running waters flow. Whenever they are granted fruits therefrom as their appointed sustenance, they will say: "It is this that in days of yore was granted to us as our sustenance!" - for they shall be given something that will recall that [past]. And there shall they have spouses pure, and there shall they abide. 25 ۞ Allah disdains not to use the similitude of things, lowest as well as highest. Those who believe know that it is truth from their Lord; but those who reject Faith say: "What means Allah by this similitude?" By it He causes many to stray, and many He leads into the right path; but He causes not to stray, except those who forsake (the path),- 26 Who, having sealed it, break God's covenant, dividing what He ordained cohered; and those who spread discord in the land will suffer assuredly. 27 How can you disbelieve in God when you were dead [lifeless] and He gave you life? He will let you die once more, then bring you back to life again, whereupon you will be returned to Him. 28 He created for you all that is in the earth, then, He willed to the heaven, and leveled them seven heavens. He has knowledge of all things. 29
